Outcomes and Objectives

1. Diagnose and complete Level 2 ASE Education Foundation tasks as listed below:

A. Research vehicle service information such as fluid type, internal combustion engine operation, vehicle service history, service precautions, technical service bulletins, and recalls including vehicles equipped with advanced driver assistance systems (ADAS).

B. Retrieve and record DTCs, OBD monitor status, and freeze frame data; clear codes and data when directed.

C. Verify operation of the instrument panel engine warning indicators.

D. Inspect engine assembly for fuel, oil, coolant, and other leaks; determine needed action.

E. Install engine covers using gaskets, seals, and sealers as required.

F. Verify engine mechanical timing.

G. Inspect, remove, and/or replace engine mounts.

H. Identify service precautions related to service of the internal combustion engine of a hybrid electric vehicle.

I. Cylinder Head and Valve Train related Tasks:

A. Identify cylinder head and valve train components and configurations.

B. Remove cylinder head; inspect gasket condition; install cylinder head and gasket; tighten according to manufacturer's specification and procedure.

C. Clean and visually inspect a cylinder head for cracks; check gasket surface areas for warpage and surface finish; check passage condition.

D. Inspect valve actuating mechanisms for wear, bending, cracks, looseness, and blocked oil passages (orifices); determine needed action.

E. Adjust valves (mechanical or hydraulic lifters).

F. Inspect and replace camshaft and drive belt/chain; includes checking drive gear wear and backlash, end play, sprocket and chain wear, overhead cam drive sprocket(s), drive belt(s), belt tension, tensioners, camshaft reluctor ring/tone-wheel, and valve timing components; verify correct camshaft timing.

II. Engine Block Assembly related Tasks:

A. Identify engine block assembly components and configurations.

B. Remove, inspect, and/or replace crankshaft vibration damper (harmonic balancer).

III. Lubrication and Cooling Systems related Tasks:

A. Identify lubrication and cooling system components and configurations.

B. Perform engine oil and filter change; use proper fluid type per manufacturer specification; reset maintenance reminder as required.

C. Perform cooling system pressure and dye tests to identify leaks; check coolant condition and level; inspect and test radiator, pressure cap, coolant recovery tank, heater core, and galley plugs; determine needed action.

D. Identify causes of engine overheating.

E. Inspect, replace, and/or adjust drive belts, tensioners, and pulleys; check pulley and belt alignment.

F. Inspect and test coolant; drain and recover coolant; flush and/or refill cooling system; use proper fluid type per manufacturer specification; bleed air as required.

G. Inspect, remove, and replace water pump.

H Remove, inspect, and replace thermostat and gasket/seal.

I. Remove and replace radiator.

J. Inspect and test fan(s), fan clutch (electrical or mechanical), fan shroud, and air dams; determine needed action.

K. Perform oil pressure tests; determine needed action.

L. Inspect auxiliary coolers; determine needed action.

M. Inspect, test, and/or replace oil temperature and pressure switches and sensors.
